n mainobjects of invention are: j

Firstg-to provide a ball cock or valve assembly for flushingtanks which eliminates thepossibillty oi backsiphonage oi' water'fromthe tank into the supply system.

Second, to provide a valve assembly for flushing-,

tanks which is very quiet in its` operation.

Third, to provide a valve assembly having" these advantages vwhich is readily adjusted. vfor pressures.

Fourth, to provide a valve assembly having these advantages which is quite simple and economical and very durable in structure.

Objects pertaining to details and economies of my invention will denitely appear from the description to follow. The invention is deiined in the claims.

A structure embodying the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. l is an elevation of a valve assembly embodying the features of my invention, portions being broken away for convenience'in illustration and to disclose structure. l

Fig. 2 is an elevation looking from the right 0i' Fig. 1, the overiiow pipe being omitted and the rell tube and fioatarm being sectioned.

Fig. 3 is a top'view, the overow pipe, refill tube, and oat being omitted.

Fig. 4 is a fragmentaryview partially invertical section showing details of the valve structure.

In the embodiment of my invention illustrated in the accompanying drawing I representsl a flushing tank and 2 the water therein when the tank is lled to a normal depth. The supply pipe or riser 3 projects upwardly within the tank and is connected to a suitable source of water supply such as a city water system. 'Ihe valve casing 4 is mounted on the upper end of this supply pipe and in the embodiment illustrated is provided with a delivery chamber 5 having a lateral delivery passage 6 terminating in a valve Seat 'I with `which the reciprocating valve l coacts. This valve is controlled by the iloat 9. the arm I0 of which is connected to the upwardly projecting arm II on the valve actuating cam or eccentric I3 which coacts with the yoke I4 on the outer end of the reciprocating valve I. lll'he valve is provided with a return. bend delivery pipe I5.

The tank is provided with ,the overflow pipe I6, the discharge end of the delivery pipe` I5 being substantially above the upper end or the plane of the upper end ofthe overilow pipe It.' -The dewater falls-fromthe top of the tube intotheV tank.

cfs (cust-104) livery end 'of the delivery pipe is preferably cut on thelbevel 'as shown at I1 in Fig. 1;

`@Inadvan'ce of the inlet v alvel I provide a regulating valve-y II which coacts with a valve seat I9 provided on theupper end of the supply pipe 8. `,'Iv'hisregulating valve I8 `is threaded for adlustment at 20 in thevalve casing and provided with`l a finger piecej'ZI to facilitate adjustment.

, AS #means Iorv quieting the flow ofvwater from successful operation on water systems of diierent v imparts to the water a rotary or swirling motion. l5

`The valve and its quieting means prevent a gushing iiow o f is opened. I I 'I'he delivery pipe lndelivers to a downwardly they water when the ball cock valve 8 tapered discharge tube 24 whichis of such length 20 that it'recei'ves the' deliverylend -of vthe delivery pipe andits lower end terminates adjacent the bottom of the tank..l Thisl discharge ltube has a lateral offset' 1orenlargement 25 at its upper end oi such dimensions as .to .fit against the side .-.of 25 the delivery pipe I6 andfsecured thereto by the vscrew 28j. i The' bottoni` of this-.Offset is? inclined inwardly-"andi merges into [the inclined wall of the discharge v,tube so that thewater' discharged from thedelivery bille-ris, discharged vdownwardly on this inclined surface i214, thatis, at the bottom of the olsetfandagainst the- Ainclinedv wall of the tapered. tube 4intogy'vhich,the .inclined bottom 2l merges;

, The diameter 2'oi' the' lower-endofthedischarge `35, tube orthe delivery opening 2,8 at.v ther bottom thereofis such that normally thefjwater, supplied from theinlet vvalvegexceeds the-y discharge 2B with the resultIv that the tube lls yand .there vis some overfiowatthe top'resultingl in submerging 40 the delivery end. kof the, delivery'pipe, thereby further silencingy vthe discharge :o f' water. However, the'samount oi' overow-shouldnot be excessive; otherwise, 'splashing-1' results as. "the It is' merely desirable to insure that the tube be filled `and slight` overilow is not objectionable vas the water runs vdown lthewall vof v.the tube.

'I'he regulatingtvalve yI8 is animportant factor in securinspsilent operation it canfbeadiusted- 50 for various-waterprellr to secure vthe proper iiow of water throughjfthe inlet valves.

' Thereturnu orgooseneck delivery pipe vhas an added feature other-.than-.the matter of v proper delivery tothefdisharge tube, namely, that when the valve 8 closes itI is entirely submerged, 'and this acts asa silencer. particularly when the valve isV nearly shut off, asat' that point very fine structureof this application has definitely met the approval of the health authorities or plumbing inspectors of certain leading cities.

The tube 24 is easily mounted, its lower end being supported by the bracket or clip -29 projecting from the lower end of the supply pipe.` The refill tube 30 is connected to the delivery pipe 3 I5 near the. top4 thereof.

I'have illustrated and described my invention inl a highly satisfactory embodiment thereof, one which secures the advantage of being positively anti-siphoning, and also a structure which is very quiet in operation, always'a desired feature in ballcocks. I am aware however that structural details may be substantially varied and still maintain various advantages of my invention.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent is: j.

1. In Ia valve assembly for flushing tanks, the combination with a supply pipe and an overflow pipe, of an inlet valve and casing therefor mounted on said supply" pipe and lprovided with a gooseneck delivery pipe, `the .discharge end of which is substantially above the top of the overflow pipe, a downwardly tapered discharge tube open at both ends and having a lateral offset at itsl upper end receiving the discharge end of said delivery pipe, the bottom of said offset being in-V wardly inclined and merging into the inclined wall' of the discharge tube so that the water from said delivery pipe is discharged downwardly against said inclined wall,th e lower end of said discharge tube being of such diameter as to restrict the delivery of water therethrough so that in the normal tank filling discharge of the valve seat and the plunger, but in this embodiment theyfthe discharge tube becom'sflled/with Water above lthe level of.y the discharge end of the de' liveryv pipe, and a refill tube ,connected to said. delivery pipe at a point aboveA the discharge end thereof. Y

2. In a valve assembly for flushing tanks, the combination with a supply pipe and an overflow pipe, of an inlet valve and casing therefor mount# ed on said supply pipe and provided with a gooseneck delivery pipe, the discharge end of which isv substantially above thetop of the over- A iiow pipe, and a downwardly tapered discharge tube open at both ends to which said delivery pipe discharges, the lower end of Said discharge tube being of such diameter relative to the'discharge vofsaid delivery pipe as to restrictthe delivery of water through the discharge tube `so that'in the normal tank filling discharge of the Avalve the discharge tube becomes filled with water above the level of the discharge end of the delivery-pipe.

3. In ra valve assembly for flushing tanks, the combination with an overflow pipe, of anl inlet valve provided with a downwardly directed delivery which opens substantially above the top 'of the overilowpipe, and a discharge tube tapered downwardly throughoutthe length thereof and open at both ends operatively associated with the discharge of said inlet valve so lthat the water discharged from the valve is discharged within the tube against an inclined Wall thereof.

4. In avalve assembly for flushing tanks, the combination of an inlet valve provided with a downwardly directed delivery pipe, and a discharge tube open at both ends and having a lateral offset in its -upper end receiving the dischargel end of said delivery pipe, the bottom of said offset being inwardly inclined and merging into the wall of the discharge tube so that the water from said delivery pipe is discharged down-A wardly against said inclined surface.

i 5. In a. valve assembly for flushing tanks, the combination of an inlet valve provided with a downwardly directed discharge, and an open ended discharge tube to th upper end of which said discharge delivers, the delivery opening in the ylower-end of said discharge tube being restricted so that it is less than the normal delivery capacity .of the valve.
